ADJUSTABLE seen-n SUP-PORT;

A plicationfll'ed Jane 6,

The invention relates to adjustable-shade supports, and has for itsobject to provide a device of this character comprisin "weight membersslidably mounted on para lel rods on opposite sides of a window frame,and provided with means forreceiving pintlesof a shade. One of theparallel rods of one side of window is rotatablymounted within the.adjacent weight member, and has its upper end provided with'a gearconnection with a horizontally disposedidrum carrying shaft, which shaftis provided with; drums over' the weight members; and with' flexibleconnections between the drums and weight members whereby upon rotationof the rotatable parallel rod, the weight members will be simultaneouslyraised or'a'llowed to-lower.

A-furth'er object is to provide a rotatable bevelled gear'in acasinga'dj acentthe lower end of the rotatable p'arallel'ro'd' and whichbevelled gear meshes with a bevelled gear carried by said rod; saidfirst mentioned bevelled gear being provided with means-for receiving aWrench forrotating' the same.

Vith the above and other objects in view the invention resides in thecombination and arrangement of parts asherein'a'fter set forth shown inthe drawing, described and claimed, it being understood that changes 1nthe precise embodiment of the invention may be made within the scope ofwhat is claimed without departing from the spirit of the invention.

In the drawing Figure 1 is an enlarged front elevation of the device,showing the same applied to facings of a window frame, andthe coversremoved from the casings of the device to better illustrate thestructure.

Figure 2 is a top plan view of one of the weight members.

Figure 3 is a perspective view of the device showing the same applied toa conven tional form of window frame.

Figure at is a detail sectionalview taken on line 1-4: of Figure 1.

Figure 5 is a modified form of gear drive for the horizontally disposeddrum ishaft, showing worm gears. I

Referring to the drawing, the numeral 1 designates a conventional formof window frame and 2 the facings at opposite sides thereof. Secured tothe facings 2 adjacent their lower ends are casings 3 and 4, whichcasings are connected to casings 5 and 6 1924'. serial No; 71812491adjacent the upper end's'of the facings'2 by I means of parallel rods 7and 8, which are vertically disposed; The rods 7 have their endsprovided with nu'ts9 for rigidly hol din'g the sa'ine, however the rod 8is rotatably mounted in bearings 10 of the casings and 6, and has itslower end provided with a bevelled gear 11, with'whi'ch a bevelled geal-12' carried by fa horizontallydisposed shaft 13 meshes. It will-be seenthat when a socket wrench is placed inthe socket 14: in

bevelled gear '17 carried by the upper end of the rod 8', consequentlywhen the rod 8 is rotated the shaft 1 5=is also rotated. Secured to theshaft 15are drums 18, which drums have secured thereto as at 19 flexiblemenubers 20 which extend downwardlythrough 2'}:

theunde rsides of the casings 5'and .6 andare secured at 21 to rings 22carried by the upper ends of .slidable weight members 23, which areslidably mounted on the rods 7 and 8. However it will be seen that therod 8 is rotatably mounted within one of the weight members, but at thesame time it vertical movement, therefore the use of a separateoperating shaft is obviated' Weight members 23 are provided with armsforms a guide 'for weight member in its 24 for the reception of thepintles 25 of a shade roller 26, and consequently when said weightmembers 23 are simultaneously raised by the rotation of the drums 18 orallowed to lower under their own weight, the shade roller maybepositioned at various elevations, and particularly to a position wherethe upper sash of a window may be lowered and a free passage ofairallowed to a room without interference fronr the shade 27.

Referring to Figure 5, the device is substantially the same as shown inFigure 1, with'the exception that the casing 6 has dis posed thereinhelical or worm gears 28 and 29 instead of the bevel gears 17 and 16,and

this form is particularly adapted where the casings 6 are secured to theinner face of a window frame, otherwise the construction and operationis the same as shown in-Figure 1.

From the above it will be seen that an adjustable shade support isprovided, which is simple in construction, positive in its operation andprovided with gear operating mechanism, which gear operating mechanismwill require sutlicient power to operate the same,

which will be greater than the powerof the weights23 and therefore theweights will stay in any position to which they may be moved. Thevarious casings and weights are preferably formed in sections so thatthey may be easily and quickly assembled on the rods, and access may beeasily and quickly had to the casings.

The invention having been set forth what is claimed as new and useful is7 '1. An adjustable shade supporting means comprising casings secured tothe opposite sides of a window frame adjacent the upper and'lower endsthereof, parallel vertically disposed rods connecting said casings,weight members vertically siidable on said rods, shade pintle receivingmembers carried by said weight members, a horizontally disposed shaftrotatably mounted in the upper casings, drums carried by saidhorizontally disposed shaft, flexible members extending around saiddrums, said flexible members having their ends secured to the weightmembers, one of said vertically disposed rods being rotatably mounted inthe casings and in the weight member, gear connections'between said lastnamed rod and the horiprising vertically disposed parallel rods atopposite sides of the window frame, weight members slidably mounted onsaid rods, a horizontally disposed rod at the upper end of the frame androtatably mounted, cable connections between the weight members and thehorizontally disposed rods, of means for rotating the horizontallydisposed rods, said means comprising gear connections between thehorizontally disposed rod, and the upper end of one of the parallel rodsand bevel gear means cooperating with the lower end of said last namedrod. I

3. The combination with an adjustable shade roller supporting device,said device comprising w'eight members slidably mounted on parallelrods, a drum rod, flexible connections between the drum rod and theweight member, of operating means for the drum rod, said meanscomprising one of the parallel. rods, gear connections between the drum:rod and last named parallel rod and means for rotating said last namedparallel rod. 1 i

In testimony whereof I hereunto aflix my signature.
